چکیده
In this work, different structures are designed based on graphene square-nanoring resonator (GSNR) and simulated by the three-dimensional finite-difference time-domain (3D-FDTD) method. Depending location number of nanoribbons (GNR), proposed can be utilized as a band-pass filter, wavelength demultiplexer, or power splitter in mid-infrared (MIR) wavelengths. The tunability suggested assemblies may controlled simply changing dimensions and/or chemical potential GSNRs. Benefiting from nanoscale ultra-compact GNRs, these basic blocks for optical computing signal processing MIR

Tunable graphene-based mid-infrared plasmonic wide-angle narrowband perfect absorber
In this paper, the periodic double-layer graphene ribbon arrays placed near a metallic ground plate coated by a dielectric layer are proposed and analyzed by the coupled-mode theory (CMT) to predict the perfect absorption response in the mid-infrared region. Numerical simulations of the finite-difference time-domain (FDTD) method confirm this effect and give the underlying physical origin. The ...

متن کاملTunable Plasmonic Nanoparticles Based on Prolate Spheroids
Metallic nanoparticles can exhibit very large optical extinction in the visible spectrum due to localized surface plasmon resonance. Spherical plasmonic nanoparticles have been the subject of numerous studies in recent years due to the fact that the scattering response of spheres can be analytically evaluated using Mie theory. However a major disadvantage of metallic spherical nanoparticles is ...

متن کاملHighly confined tunable mid-infrared plasmonics in graphene nanoresonators.
Single-layer graphene has been shown to have intriguing prospects as a plasmonic material, as modes having plasmon wavelengths ~20 times smaller than free space (λp ~ λ0/20) have been observed in the 2-6 THz range, and active graphene plasmonic devices operating in that regime have been explored. However there is great interest in understanding the properties of graphene plasmons across the inf...
